REM By default the script will use JAVA_HOME to determine which java
REM to use, but you can set a specific path for Solr to use without
REM affecting other Java applications on your server/workstation.
REM set SOLR_JAVA_HOME=

REM Increase Java Min/Max Heap as needed to support your indexing / query needs
set SOLR_JAVA_MEM=-Xms512m -Xmx512m

REM Enable verbose GC logging
set GC_LOG_OPTS=-verbose:gc -XX:+PrintHeapAtGC -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintTenuringDistribution -XX:+PrintGCApplicationStoppedTime

REM These GC settings have shown to work well for a number of common Solr workloads
set GC_TUNE=-XX:NewRatio=3 ^
 -XX:SurvivorRatio=4 ^
 -XX:TargetSurvivorRatio=90 ^
 -XX:MaxTenuringThreshold=8 ^
 -XX:+UseConcMarkSweepGC ^
 -XX:+UseParNewGC ^
 -XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 ^
 -XX:+CMSScavengeBeforeRemark ^
 -XX:PretenureSizeThreshold=64m ^
 -XX:+UseCMSInitiatingOccupancyOnly ^
 -XX:CMSInitiatingOccupancyFraction=50 ^
 -XX:CMSMaxAbortablePrecleanTime=6000 ^
 -XX:+CMSParallelRemarkEnabled ^
 -XX:+ParallelRefProcEnabled

REM Set the ZooKeeper connection string if using an external ZooKeeper ensemble
REM e.g. host1:2181,host2:2181/chroot
REM Leave empty if not using SolrCloud
REM set ZK_HOST=

REM Set the ZooKeeper client timeout (for SolrCloud mode)
REM set ZK_CLIENT_TIMEOUT=15000

REM By default the start script uses "localhost"; override the hostname here
REM for production SolrCloud environments to control the hostname exposed to cluster state
REM set SOLR_HOST=192.168.1.1

REM By default the start script uses UTC; override the timezone if needed
REM set SOLR_TIMEZONE=UTC

REM Set to true to activate the JMX RMI connector to allow remote JMX client applications
REM to monitor the JVM hosting Solr; set to "false" to disable that behavior
REM (false is recommended in production environments)
set ENABLE_REMOTE_JMX_OPTS=false

REM The script will use SOLR_PORT+10000 for the RMI_PORT or you can set it here
REM set RMI_PORT=18983

REM Anything you add to the SOLR_OPTS variable will be included in the java
REM start command line as-is, in ADDITION to other options. If you specify the
REM -a option on start script, those options will be appended as well. Examples:
REM set SOLR_OPTS=%SOLR_OPTS% -Dsolr.autoSoftCommit.maxTime=3000
REM set SOLR_OPTS=%SOLR_OPTS% -Dsolr.autoCommit.maxTime=60000
REM set SOLR_OPTS=%SOLR_OPTS% -Dsolr.clustering.enabled=true

REM Path to a directory where Solr creates index files, the specified directory
REM must contain a solr.xml; by default, Solr will use server/solr
REM set SOLR_HOME=

REM Sets the port Solr binds to, default is 8983
REM set SOLR_PORT=8983
